Reading
Hydropower dams are massive concrete walls placed inside rivers or streams to hold back water. Holes in the dam allow controlled amounts of water to pass through and as it moves through these holes, it passes through a machine, which converts that movement into electricity. Dams are incredible engineering marvels that represent one of the most beneficial and effective forms of electricity creation today.
First, dams positively impact the environment. Once constructed, these massive walls hold back tremendous amounts of water, forming artificial lakes. These lakes produce not only a wonderful habitat for fish but also a beautiful recreation area for local citizens, which serves to help the local population stay aware and respectful of nature. Additionally, through irrigation, these lakes bring to life millions of acres of ground that would otherwise lie barren.
Second, the power generated from a dam produces no harmful pollutants. This is in direct contrast to the dominant source of electricity production today—coal power plants, which are the leading cause of smog, acid rain, and air pollution. One large dam generates roughly the same amount of electricity as a typical coal plant. Consequently, dams, by replacing these plants, eliminate, among several other toxic pollutants, an average of 3.7 million tons of the global warming gas carbon dioxide per year.
Third, dams create no financial burden for the community. Because dams generate electricity and provide irrigation water for local agricultural concerns, they provide two means of bringing in revenue for owners. Combined, this revenue more than covers the significant expenses incurred during operation of the dam, resulting in significant profits. For example, the Grand Coulee Dam in Washington produces approximately 15 billion in revenue per year and requires only 5.7 billion in operating costs.
The reading claims that Dams are incredible engineering marvels that represt on of the most beneficial forms of electricity creation today and provides three reasons of support. The professor states that more research are necessary and the points in the passage have many drawbacks and he refutes each of author's reasons.
To begin with, the article avers that dams have positive impact on the environment. In contrast, the lecturer opposes this point by saying that the environment does suffer. He explains that during build dams, the river's way will divert that present problem to migration of fishes, so fishes will lose their way and die. He adds that after finishing the building the force of water will be slow. Because fishes required more fast to lie their eggs, this will affect their reproduction.
Second, the reading posits that the power generated from dams produces no harmful pollutants. However, the professor counters this point by discussing that artificial lakes periodically floods during the year that leads to die of plants. In fact, these dead plants will decompose and release methane that is global warming gas. In addition, destroying plants will participate in decrease releasing CO2.
Last bu not least, the article asserts that dams create no financial burden for the commnity. Conversely, the lecturer cast doubt on this point by explaining that the community suffer financially. He mentions that dams create artificial lakes that flood and the local residents will suffer from these floods and they must be relocate, so the government aids residents for restore their houses that costs more money.
